Linkin Park have been in the studio and are expected to drop a new single called "Heavy" very soon. The band has talked about experimenting more on this album, and due to the pop nature of this track we can only assume that at least some parts of the album will do just that. 

When discussing this song, other members of the band discussed bringing in a female vocalist to harmonize with Chester. Based on the sound of the track, I think it's a safe assumption the female vocalist will be from the pop realm.
